MACHINE FOB FILLING CARTRIDGE-BELTS.

Specification of Letters Patent.

Patented Apr. 25, time.

Application filed July 6, 1912. Serial No. 708,070.

To all whom it may concern:

Be it known that I, WILHELMI Soxxnnao, engineer, a subject of the King of Prussia, residing at No. 14: Mindenerstrasse, Charlottenburg, near Berlin, Germany, have invented certain new and useful Improvements in Machines for Filling Cartridge- Belts, of which the following is a specification.

This invention has for its objectan improved machine for filling cartridge belts, according to which the 'feed and adjustment of .the belt are effected mainly by a pocket opening pin whereby greater exactitude in the adjustment of the belt is obtained.

An embodiment of the invention is illustrated by way of example in the accompany ing drawing, in which:

Figure 1 is a .plan of the machine. Fig. 2 is a longitudinal section on the line 22 in Fig. 1, and Fig. 3 is a cross section on-the line 3-3 in Fig. 1.

In a casing 1 a shaft 2 rotatable by means of a handle 9 or in some other suitable man nor is mounted and upon it a. roller 3 is fixed. The roller 3 produces the reciprocating movement of the slide 8 parallel with the axis of the shaft 2 by means of a pin and roller 11 engaging a groove 12. and also the rotation of the lever 13, pivoted to the casing 1 and terminating in a jaw i0. about its pivot it by means of the pin and roller 16, which engage in a groove 17 on the roller The arm 18 of the second retaining lever 19, which is provided with a roller 21, is constantly held against the periphery of the roller 3 by means of a spring. The pe riphery of the roller is tapered so that when the roller "21 rests on this tapered portion the retaining lever 19 is rocked upward about its pivot 22 by this spring.

The. shaft 2 also carries the cam plate 23 which acts on a roller '24 of a double slide vertically displaccable 1n the casing 1:

this slide is constantly drawn downward by a' spring 26 and its upper tapered end passes through an opening in the table 28.

The retaining levers and slides cooperate. in such a manner that the slide 8 and the retaining lever 19 on the one hand and the slide 25 and the retaining lever 1:1 on the other hand temporarily hold the belt +1be tween them or release it.

, connecting rod 30 engages a slide On the right hand end of the shaft the crank 29 is mounted'which by means of a 32 which is horizontally displaceable beneath the table 28 in the casing 1. This slide 32 reciprocates at right angles to the axis of the shaft and supports the pin serving for opening and spreading out the pockets in the belt and also the cartridge slide 34. The ear tridge slide removes the cartridge which for the time being is the lowest in a reservoir and inserts it into the pocketopened by the pin 33.

The pin is fixed in a slide 36 which is displaceably mounted on the slide 32 parallel with the axis of the shaft and in an arm 3'7 of the slide 3 at right angles to this direction. The pin 33 is therefore displaced by the slide 8 parallel with the axis of the shaft and by the slide 32 per -ieinlicularly thereto.

The cartridge slide 34 is mounted on the slidewith a limited capacity for movement parallel with the axis of the shaft and is constantly pressed outward by a spring 39. It is also acted upon by a guide lever 43 which temporarily holds it in the right hand end position.

The machine operates as follows: Proceeding from the position of the machine illustrated in the drawing when the crank is rotated the pocket opening pin -penetrates the pocket tightly stretched between the grippers and is simultaneously moved forward in the feed direction together with. the grippers S, 19. As soon as the pin has reached the front grippers 25 they move upward and downward so that the pin 3nd the grippers S. 19. conjoiutly are able to displace the belt until the pin reaches the place previously assumed by. the cartridge last inserted in the belt. The lever 13 then again descends and simultaneously the double slide 25 moves upward so that the belt is held on the two intermediate walls between the pocket to-be tilled while the pin is withdrawn and a cartridge is inserted into this pocket by means of the cartridge slide 34. After the pin 33 has left the pocket the grippers 8. 19. the latter in the raised position. move back and the pin returns to its initial position.

lVhat we claim and desire to secure by Letters Patent of the United ,States is:

1. In a machine for filling cartridge belts, belt feeding means adapted to grip the belt, and means adapted to open the pockets in the belt and also to displace the belt in the direction of feed.

2. In a machine for filling cartridge belts, belt feeding means adapted to clamp the belt between them and pocket opening means adapted in conjunction with said feeding 12163118 to displace the belt in the direction of 3. In a machine for filling cartridge belts. means adapted to clamp the belt between them at both sides of a belt pocket, and meansadapted to open the belt pockets, said clamping means and said pocket opening Lneians operating in conjunction to feed the 4. In a machine for filling cartridge belts, meansvadapted to clamp the belt between them, means adapted to open the belt pockets, and means adapted to displace said clamping means and said pocket opening means in the direction of feed.

5. In a machine for filling cartridge belts, means adapted to open the belt pockets and also to displace the belt in the direction of feed, and means adapted to clamp the belt between them at both sides of a pocket during the opening of same.

. 6. In a machine for filling cartridge belts, means adaptedto open the belt pockets and also to displace the belt in the direction of feed, means adapted to introduce cartridges into the pockets, and means adapted to clamp the belt between them at both sides of a pocket during the introduction of a clamp the belt between them at both sides of a pocket during the opening of same and during the introduction ofa cartridge into same,

8. In a machine for filling cartridge belts,

reciprocating pocket opening means adapted to displace the belt in the direction of feed, and means adapted'to clamp the belt between th'em at both sides of the opened pocket during the idle return movement of said pocket opening means.

9. In a machine for filling cartridge belts, reciprocatin 'pocket opening means adapted to displa e (5% means to pockets. and means adapted to clamp the belt between them at both sides of a pocket during the insertion of a cartridge into said pocket and during the idle return stroke of said pocket opening means.
